However, the spatial distribution of stress and strain at any given instant is non-uniform and its variations with increase in punch penetration are quite complex. In this work, the digital image correlation (DIC) technique is integrated with small punch test for in-situ full field strain measurement in the bottom surface of the specimen. The DIC results reveal that with the progression of deformation, the peak equivalent plastic strain at the bottom surface shifts from the center of the specimen to a characteristic radial location, where the strain rapidly builds up and concentrates leading to instability and cracking. Combining DIC-based strain results with finite element model-based stress estimation at the characteristic radial location, a methodology for determining the stress–strain curve from small punch test is formulated and the outcomes are compared with tensile test results for four different metallic alloys.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"21 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XRD investigation at room temperature using Rietveld refinement indicates rhombohedral crystal symmetry (#R (overline{3}) c) with a crystallite size of 30 nm. Scanning electron micrographs demonstrate a homogeneous distribution of well-grown grains with defined grain boundaries, which is critical for understanding the conductivity mechanism. The compactness of the grains verifies the creation of a dense sample, which could be one of the factors contributing to the observed physical attributes. The purity and uniform distribution of all constituent elements were confirmed using the energy-dispersive X-ray analysis spectrum and color mapping, respectively. The Maxwell–Wagner polarization effect is observable at low frequencies. The analysis of impedance and modulus plots indicates the existence of a negative temperature coefficient of resistance and a non-Debye relaxation process, respectively. The existence of a thermally activated conduction mechanism in the investigated sample is supported by the analysis of AC conductivity as a function of temperature and frequency. The semiconducting nature is supported by the existence of semicircular arcs in both the Nyquist’s and Cole–Cole plots, suggesting that they would be good candidates for energy storage devices. The presence of NTC thermistor character for temperature sensor applications is suggested by the resistance versus temperature investigation.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"184 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the quick deterioration of magnesium alloys results in a rapid decline in mechanical properties, restricting their clinical application. Recent advancements, particularly in the integration of nanoparticle reinforcement, have enhanced mechanical strength while preserving the inherent toughness. These composites also show impressive corrosion resistance and compatibility with biological systems. However, uniformly dispersing nanoparticles as reinforcements within the Mg matrix and achieving the desired properties present significant challenges. Consequently, selecting appropriate magnesium nanocomposite production methods and identifying biodegradable, biocompatible, and osteogenic reinforcements are of utmost importance to overcome these obstacles and enhance mechanical, corrosion, and cytotoxic properties relevant to specific applications becomes imperative. This review investigates a range of fabrication techniques and types of reinforcement, analysing their impact on the mechanical properties, corrosion resistance, and biocompatibility of magnesium nanocomposites. Additionally, it investigates potential applications and proposes future research avenues for magnesium nanocomposites.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"18 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field emission scanning electron microscopy (FE-SEM) was employed to examine microstructural changes, complemented by energy-dispersive spectroscopy. The FE-SEM micrographs revealed approximately 1.5% porosity, confirming densification of about 98.8% through Archimedes' principal, and X-ray diffraction identified a body-centered cubic solid solution phase. Furthermore, the melting point of the prepared high-entropy alloy was determined through differential scanning calorimetry. Assessing the mechanical robustness and tribological behavior, a Vickers microhardness tester and a ball-on-disk tribometer were employed for the sintered sample at 950 °C.

The cross section microstructures, the effective connection height (ECH), and the effective connection width (ECW) were characterized. In the meantime, the thermal mechanically affected zone/stir zone and the fracture path were also described. The lap joint’s hardness, shear strength, and failure mode were analyzed by optical microscope. It was found that the effective connection area (ECA = ECH × ECW) had a good correlation with the tensile shear property. At 1200 rpm, the plunge depth benefit improved the tensile shear strength of the welded joint, while at 1500 rpm, it had the opposite effect. The optimal welding parameters of 5 mm diameter joints were 2100 rpm of rotation speed and 1.0 mm of plunge depth, under those the tensile shear force of the joint was 3196.9 N. The shear-plug type fracture path was different at different rotational speeds. The fracture path of the welded joint at high rotational speed expanded from the stirring zone at 45° finally; while, the fracture path of the welded joint at low rotational speed fractured from the thermal–mechanical affected zone finally. The fracture path at high speed was more complex than at low speed.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"1 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for achieving improved joint efficiency and dissimilar joints, secondary heat sources are being used to make the materials softer to enhance the mixing through stirring. In this present work, a comparative study of multiple hybridization techniques to Friction Stir Welding was performed by utilizing two different energy sources viz. resistive heating through electric current and ultrasonic energy (UE). Different combinations of the hybridization studied for utilizing the multiple hybridization technique to the FSW process for improving the weld efficacy and defects-free weld even in case of dissimilar joints. A comparative study of the mechanical properties obtained by varying the process parameters have been performed. Three process parameters have been selected including UE (10 kHz), electric current (75–125 Amps), tool rotational speed (400–600 rpm), and tool transverse rate (30–50 mm/min). A significant improvement in the mechanical behavior has been monitored by adding electric current to the UAFSW by an in-house developed fixture. Similar optimistic results in the improvement of the property have been found by adding UE to EAFSW. A comparative study in the mechanical property has been presented to explain the improvement in the property.
